HDZero Halo 4in1 70A ESC – BLHeli32 / AM32, 3–8S, 20x20mm, Split PCB, 100A Burst for FPV Racing Freestyle

Overview

The HDZero Halo 4in1 70A ESC is engineered for high-performance FPV pilots seeking uncompromising power, thermal efficiency, and reliability. With a continuous 70A output per motor and 100A burst capability, it’s purpose-built for elite-level racing and freestyle drone applications. Choose between BLHeli_32 and AM32 firmware versions to tailor your flying experience.

This ESC features an advanced split-board architecture that separates control and power stages, optimizing heat dissipation and minimizing electrical noise. It uses 3oz copper across 8 PCB layers with an integrated copper bus bar for efficient current flow and sharper throttle bursts. Clean power delivery isolates the MCU and drivers from voltage spikes, reducing the risk of ESC failure, brownouts, or motor damage.

With conformal coating for environmental protection and dual-sided solder pads for installation flexibility, the HDZero Halo 70A ESC is crafted for durability in the most demanding FPV builds.
